I have been casting bullets for over 30 years so I do have some experience with it. All the moulds that I have used in the past were for .30 cal, .357, and 44's.
Never had much problem with any of those.
Now Ive started trying to cast for my 40-65's and my 45-90. I am not having good luck with these at all. I cant get the base to fill out properly.
I drilled out the spout on my dipper to 3/16 and set the alloy temp to 800.
BTW these are all iron moulds. The Lyman moulds are bad about sticking too but I recall that Lymans always were. I'm using 30-1 alloy.
Any ideas?
